This invrniion rolaies lo a radio iono arm giiinehmordi'or ihonogruphs and has for its objrcito provide, means whereby ihe sound amplifier oi the phonogrnphs may be ourpioyed oiihor \ri'lh ihe sound reproducing menns oi ihe phonograph or of n radio roooiving sol.

ll-lore particularly if is iihe objori of the :niion to provide an attachment in which diroet communication may be esloblinhed hotwoon iiho sound box or other sound ampli- "lying; means of tho phonograph and either tho lone arm of the phonograph or 'ihe mirropboi'io or other sound reproducing means of iho ridio receiving set Willi the above and other. objects in View tho invention may be said to comprise the fievico illmsirniod in (he accompanying; drawi now heroinnilor (lesoi'ibod and particularly :e' forth in the appended claims, together Willi snrh variations and ,modifientions ihorooi as will ho apparent lo ono skilled in tho Zli'i to which iho invention opporiiainn.

(one arm is held in plare in ihe extension (3 and HS turning movpmont in limitod by means of ihe pin 8 fixed to the. wall of ihe e'XfenPion G and projoeting inwardly through a oircnmferentially extending slot 9 in the portion of the lone :nrin filling within the extension 6. The outer end of the tone arm 7 carries the sound reproducing member 10 which has n noodle 11 ongagenble with the record on tho turntable 2.

The outer end of the member 4 is open and rotatably fitting Within the member 4. is n lnbnlor exiension 12 which is held in place in the tubular member 4 and allowed n limited rotary movement by a pin 13 carried by the wall of the tubular member 4 and projecting inwardly therefrom into a, slot 14- oxtending circinnferentially of the Wall of fhe tubular member 12. The tubulnr member 19; has an opening 15 in its wall which is of the some size no the opening between the tubular member 4 and its looeral extension 6 and the rotor movement of the tubular member 12 is sucn that the opening 15 may be shiftocl from o osilion in registry wlih the opening; loading to the oxtonsion 6 or entirely oleor of said opening. When the tubular membor 12 is in one 081- lion communication will ho ostabiiohe" between the "tubular member 4 and tho hollow tone arm 7 and when the tubular member 12 is owned in the opposite direction, the amount permitted by the slot M the opening 15 will be out of registry with the opening in this wall of tho tubular member 4;- ond rho hollow tone, arm 7 will bo cut oil frnn the mombor l and from the sound box \(ALE the phonograph. The tubular onion oion 2 153 open ended and has iii-reducedouior and 18 adopted to receive. a radio microphone attachment 17 or oiher sound ropmducing ononnn of the radio receiving set.

"When tho phonogrnph is in use the exionoio g ,12 will be so positioned that the oponing 15 thereof registers with the openinn" from ihe tone, arm \into the section 4 so iiifli} the sounds reproduced from the record oro irnnsrnitiod through the tone arm, the member land elbow 3 into the sound box 1. When. i l in desired to em 10y the sound am.- plilyinlg; moons of the p onograph in connociiio with the radio roceiving sot, the-h1- bulor extension 12 will he turned to the calthe scund box and the sounds emitted from the microphone 17 or other sound reproducing means of the radio receiving set will be transmitted directly through the attaohment into the sound box 1.

I'Iaving described my invention, 1 claiml. A radio and tone arm attachment for phonographs comprising a tubular member having open ends, one of which is adapted to be placed in communication with the sound amplifier ot a phonograph, said tubular member having an opening in its wall, a hollow tone arm carried by the tubular member and communicating therewith through said inner end extending into the tubular member and movable therein and its outer end adapt ed to receive a radio sound reproducing attachment, said tubular extension having an opening in its wall adapted to be moved into and out of registry with the opening in the tubular member.

2. A radio and tone arm attachment for opening, and a tubular extension having its phonographs comprising a tubular member having anopening in its wall whereby the extension may be turned to open or close the opening, said tubular extension being adapted to receive a radio taohment.

3. A radio and tone arm attachment for phonographs comprising a tubular member having open ends, one of which is adapted to be placed in communication with the sound amplifier of a phonograph, a hollow tone arm carried by the tubular member and communicating with the tubular member t-luough an opening; in its wall and a tubulur extension movably mounted in said tubu lar member, said tubular extension having" a part adapted to open and close said opening.

4. A radio and tone arm attachment comprising interfit'tine tubes one having a rotative movement within the other, the outer tube having an opening in its wall and the inner tube having an opening adapted to be moved into and out of registry with the open ing in the outer tube, and a hollow tone arm carried by the outer tube and commun1- eating with the opening of said outer tube, one of said tubes being adapted to be placed in communication with the sound amplifier of a phonograph and the other to receive a radio sound reproducing attachment.

In testimonywhereof, I hereunto aiii my signature.
